Effect of Ethanol Extract and Ethyl Acetate Fraction of Soursop Leaves administration on Malondialdehyde Levels of Alloxan-Induced Rat Endocrine Cells

Soursop leaves (Annona muricata L.) contain many antioxidant compounds such as phenols and flavonoids that play an active role in inhibiting oxidative stress and can inhibit damage and death in cells, tissues, or organs. The objective of this study was to determine the effect of soursop leaf ethanol extract and ethyl acetate fraction effect on malondialdehyde levels and the quantity of pancreatic endocrine cells in male rats (Mus musculus) induced with alloxan. Method, the test animals were divided into seven groups (n=4). The normal control group was only given feed, the negative control group was given CMC-Na solution, the positive control group was given vitamin C dose of 50 mg/kg.BW, treatment group I was given soursop ethanol extract dose of 50 mg/kg.BW, treatment group II was given soursop ethanol extract dose of 100 mg./kg.BW, ethyl acetate fraction treatment group III was given soursop ethyl acetate fraction dose of 25 mg/kg BW, and treatment group IV was given soursop ethyl acetate fraction dose of 50 mg/kg BW. Results showed that the administration of ethyl acetate fraction of soursop leaves at a dose of 25 mg/kg BW showed the most effective potential significantly (p<0.05) in reducing malondialdehyde levels and cell death. In conclusion, administering ethanol extract and ethyl acetate fraction of soursop leaves to rats which experiencing oxidative stress in their pancreas can stimulate and increase regeneration of endocrine cell in all rat groups. This is proven by a decrease of malondialdehyde levels and the number of necrosis cell necrosis. 1
